lThis invention. relates to ador ttings for i' the rotary drums of'washing machines.V Such door fittings asconstructed hereto-Y fore include al flor* rproperr hingedly' 'con-r nected to the drum and restrained against outwardmovement by hinges located at'one longitudinal edge and byl fastening means located at" the other longitudinal edgeand at the lateral 'edges. ,y y In'such a fitting vthedoor `isV-disposed wholly external to the drum and' forces tending to,movev the vdoor .outwardly are necessarily absorbed by the hinges and fastening means so that the hinges and fastenyings are unduly worn and require frequent replacement. f

vThe primary object ofthe inventionjis. to provide means for securing the door rigidly in closed or operative position indey pendently of the hinges and the fastening means sol that .the hinges andthe fastening means are lunaffected by the forces tending In the accompanying drawing Fignlfis a fragmentaryy elevation of a door" and a por#v tion of a drum, and Fig. 2 a fragmentary section' on the line A'k-A of Fig. "1.

In the constructionshown the door proper l is mountedl on the drumA 2 to perform angular and, circumferential' movements relatively thereto', .and is'4 so' shaped and vdi#y mensioned `as to ybe'inseitable into the doorf fac-e of the drum 2.

opening 3 with -the longitudinal` marginal edges 4, 5 engageable with the 'inner surfy The door is mounted on hinges spacedk longitudinally thereof ,and each comprising a strap 6 secured to thev door land fa hinge pin 7 fixed to the strap 6 and ypt enetiating an eye bolt8 which is slidable in a socket meinber v9 secured to the drum. It will be seen that the door is free to perform angular movement about `the hingepins 7 so as vto expose or to close the door-opening and also sliding circumferential movement relatively The door when -closedis `cammed out-l wardly so that the marginal edges 4,5 forcibly engage the inner'surfac'e of the drum 2' by two sets of wedge-'like cams l1 0 solid with the drum 2 and 'located kone set at each lat- .eral boundary of the door-opening. Co-operating with they camslO are cani followers constituted by armsll fixed to theouter side of the door l. The acting faces of the cams are disposed substantially tangentially For locking lthe door against circumfer ential movement relatively to.v the' drum it there .is provided a bolt l2 mounted to peri forni sliding movem-ents in a'soclret 13 secured tof` theV drum. 2 .at the longitudinal boundary of the door-opening remotey from the hinges and engageable With'a perforated i vlug l/ly mounted on the door 1.

1 5 denotes the usual washing machine casing enclosing the drum.

I claiinz-` nl. Ina washing machine,- a rotary drum having av door-opening, a door in sertable in'- to `the openingand having at one longitudinal edge arhinge connection with thev drum,v door `vfastening means at the other longitudinal edgeof the door, and co-.operagin'fof theopening without effect von ythe hinge connection lor fasteningmeans. 1

2. In a washing machineyawrot'ary drum having a door-opening, aldoor' ilnsertable in-y tothe openingand engageable at its margin with the inner surface of the drum, a conf neetion between the door and 'the'drumzpen mitting relative movement of the door and the drum,l and meanseifecti've 'on relative movement ofthe door and drinn forv urging theA doory outwardly to close the opening. f

3.* In 1a washing machine, a yrotary drum having aldoor-opening, Vsockets fixed to the drum adjacentjto the opening, a door in'- sertable `into the-opening, eye bolts hingedly mounted onfthe door and engageablev in lsaid sockets permitting angular and circum-i fer'enftial-v movements of the door relatively'y to thel drum,means eEective onrelative cir- I cumferential movement ofthe' door and the drum for camming the doork outwardly to close' the opening, lv'and means for locking the f l door lagainst retrograde ycircumferentiall movement relatively Vto fthedrum.

y1l. In yawashing machine, a rotary drum having .-a l'door-opening, a door insertable in'- to theopeningand havinga connection with the drum permitting the door to perform` angular 'andI -circumferential,` movements relatively to thev drum, ycams. located adja-y cent to the lateral boundaries of the opening, cam followers fixed to the door and engageable with Said cams, whereby circumferential movement of the door in one directo is accompanied by outward movement of the door to close the opening, and means for looking the door against retrograde circumferential movement relatively to the drum.

5. In a washing,` machine, a' rotary drum having a door-opening, a door nsertable into Said opening and connectible with the drum to perform angular and circumferential movements relatively to the drum, means effective on relative circumferential movement of the door and the drum for camming the door outwardly to close the opening, a perforated lug secured to the door, and a bolt rsldaloly mounted on the drum and engagealole with said lug to lock the door against retrograde circumferential movement relatively to the drum.

ln testimony whereof I have signed; my name to this specification.
